Western S-Shank Curb
The S shape on the shanks of this bit contributes to the weight, balance, and leverage when the rider pulls back on the reins. The S actually makes this a more severe bit than a bit with the same length of straight shanks, such as the grazing bit. This bit needs to used carefully to avoid hurting the horse. Theport in the middle of the mouthpiece amplifies the rein aids and provides some relief to the horse’s tongue.
